Among the many amazing details (detail from a photo token by Edoardo Rodriquez) we photographed for the Terramata file in the Foggini Cave (Gilf Kebir, Egypt) but we do not posted on the web, there is what every visitors perceived as the representation of a pond or a lake. Is it the lake of the swimmers? In the past, professional rock art scientists contended that there is no proof that the human figures in the swimmer's cave really represent swimmers as they were interpreted by Count L. de Almasy and the explorers of the '30. The Foggini Cave shows "additional" swimmers, a representation that we call a "river" with the reflection of people gathered on it and the unique and single representation of "a Lake". Probably, the rock art scientists will not agree on our amateurish interpretation but, after having encountered a lot of  wind-worked "playa" sediments in the Western Desert, having read that the Saharan Neolithic was a sort of "lacustrine culture" we were so prone to find a lake in the hundreds of paintings of the Foggini Cave that we saw in the above painting was a nearly photographic representation of a prehistoric lake once thriving of life in the deep heart of the Sahara!
